Cho, Hyesun. 2013. Effects of tonal distance and speech rate in the phonetic realization of Kinande H tones. Studies in Phonetics, Phonology and Morphology 19.3. 501-527.
The effects of time pressure in the realization of the fall and the rise between H tones in Kinande are examined, through a production study of one Kinande speaker. Phonetic realization of tonal languages such as Kinande is relatively less studied, though their phonological patterns have been more studied. Two types of time pressure of different nature are tested: tonal
distance (phonological) and speech rate (phonetic). For the former, the number of syllables between two H tones is varied from zero to three. For the latter, speech rate is varied among fast, normal, and slow rates. The two types of time pressure
showed similar effects in some respects, e.g., reduction in pitch magnitude under time pressure, relatively consistent slope of the fall. There were also differences in the effects of two types of pressure: the slope of the rise becomes steeper in closer tonal distance, but it becomes shallower in faster speech. Overall, alignment is less affected than pitch magnitude, under both types of time pressure. This suggests that in a tonal language such as Kinande, where tones are contrastive, tonal alignment is important to maintain than pitch magnitude. (Seoul National University)
